Some thoughts - guessing you will have a car
Sonesta in Maho - close to airport, AI, but with a summer rate who cares if you miss some meals and no foraging for food and drink if you are a 1st timer
Horny Toad - no recent info, but on beach, inexpensive
These 2 options put you close to provisioning, charter and resto / bars and airport if you hae to pick up any incoming crew
Could try Grand Case area or Orient - maybe La Playa
Let us know what you choose
